PRESTON M. BRUNER, OF'SI. LOUIS, MISSOURI.

CABLE RAILWAY.

SPECIFICATION forming part of Letters Patent No. 374,775, dated Decemberl?, 1887.

Application filed March 10, 1887. Serial No. 230,440. (No model.)

T0 aZZ whom, it may concern:

Be it known that I, PRESTON M. BRUNER, of the city of St. Louis, in theState of Missouri, have invented a certain new and useful.

Improvement in Cable Railways, of which the following is a full, clear,and exact description, reference being had to the accompanying drawings,forming part of this spectication, and in which- Figurelis a verticalsection through my improved railway, taken on line I I, Fig. III. Fig.II is a detail top view, part in horizontal section. Fig. III is adetail View looking at the inside of the upper part of the conduit, andis, so to speak, a section taken on'lineIII III, Fig. I. Fig. IV is adetail vertical section\ taken on line IV IV, Fig. III. Fig. V is asimilar View illustrating a slight modification. Fig. VI is anothersimilar view illustrating another slight modification.

My invention relates to certain improvements in cable railways; anditconsists in features of novelty hereinafter more fully described, andpointed out in the claims.

Referring to the drawings, 1 represents the tracks fitting in chairs 2,having horizontal perforated projections or bases 3, through which passbolts or rods 4 with nuts 5 on their outer ends.

6 represents the conduit ortube,made, preferably, of concrete,7, andyokes or plates,8,ras

l in my patent, No. 345,616, issued July 13,1886,

the yokes or plates having in this case'lugs 9' to receive rods 10, thatsurround the yokes and are provided with nuts 11, by which they may betightened. The function of these rods 10 is the same as that of thebands or straps L of my patent referred to. The inner ends of the rodsor bolts 4 are connected to the yoke of the tube or conduit, andtend,-by tying the tube to the chairs of the track, to prevent theclosing of the slot, and by turning the nuts 5 the slot can be to acertain extent enlarged.

12 represents arms corresponding to the arms i O of my patent mentioned.Their function is described in the patent.

Inside of the upper part, 13, of the tube or conduit are platesl4,connected to the conduit at their lower edges and having heads 15 onthe upper edges. The heads 15 preferably fit under the inturned edges 16of the conduit, (though they may t outside, as shown in Fig.

V,) and. they regulate the width ofthe slot through which the grippasses and through which vehicle-wheels are prevented from passing.These heads 15 prevent, to a great extent, the entrance of dirt and mudinto the spaces between the plates and sides of the are connected bybolts 17 near their upperv edges to the part 13 of the conduit. Now, incase of frost causing the expansion of the roadbed, the part 13 of theconduit will be compressed; but the plates 14, which regulate the sizeof the grip-opening of the slot, will-re-y main unmoved, or should theymove, owing to frictional contact with the part 13 or to their beingconnected thereto, they can be easily and quickly set apart by the bolts17, the nutsof which can be reached through the slot. The slot will thusbe, regardless of temperature, always the proper size, or shouldit varyit can easily be regulated.

As stated,the heads of the plates 14 may fit outside of the conduitproper, if preferred, (see Fig. V,) andinstead of the plates beingconnected to the conduit, as shown in Figs. I and IV, where they havebases 21, through which pass bolts 22, they may be connected, as shownin Fig. VI, by bolts 18 and washers 19. When connected as shown in Figs.I and IV, they would have openings or perforations 20 (see Fig. III) asuitable distance apart to permit the passage of dirt and mud that mayget between them and the upper part, 13, of the conduit. With the forniof connection shown in Fig.VI,the dirt and mud would pass down throughbetween the various washers 19, which would be some distance apart.

23 represents rods connecting the part13 of the conduit to the sleepersof the tracks. They have nuts 24 at both ends, and by turning on thesenuts the part 13 of the conduit may be expanded, if desired. The plates14 are perforated at 25 (see Fig. IV to allow access to the inner nuts,24.

The road-bed consists of blocks 27, extending from either side of theconduit to the rail IOO on that side. They may be made narrow, as Shownon the left-hand side of Fig. II, or wide, as shown on the right-handside. Between the outer ends of these blocks and the ties of the tracksare placed strips 28, which are triangular in crosssection, andpreferably have concave inner faces that receive convex faces formed onthe outer ends of the blocks 27. The object of this construction is thatwhen the frost in the street between either rail and the sidewalkexpands the blocks 27, instead of being forced in a horizontal planedirectly against the conduit, will rise or lift at their outer ends,owing to the shape of the strips, and thus the strain that will bebrought upon the conduit by the expansion of the street between eitherrail and the sidewalk is prevented.

I claim as my invention- 1. In combination with the conduit or tube of arailway, the plates 14, when mud or dirt passages are left or providedat the bottoni of said plates, substantially as and for the purpose setforth.

2. In combination with the conduit or tube of a railway, the plates14,having openings to permit the passage of mud and dirt formed byremoving portions of the plates at their lower edges, as set forth.

3. In a railway, the conduit consisting of the combination of theconcrete, plates embedded in the concrete and having perforated lugs,rods embracing the plates and passing through the lugs, and nuts on therods, Substantially as and for the purpose-set forth.

4. In a railway, in combination with the conduit and the track, theblocks 27Yand strips 28, formed substantially as and for the purpose setforth.
